The Fuel Treatment Evaluator (FTE) 3.0 is a web-based tool that simulates uneven-aged and even-aged silvicultural treatments on timberland in 12 western states. This tool simulates treatments to reduce forest fire hazard to specific target levels and identifies the volume of biomass removed, harvesting costs, and estimated biomass revenue. As the basis for the simulation, FTE 3.0 uses data from approximately 37,000 forest plots surveyed by the USDA Forest Service Forest Inventory and Analysis (FIA) program. The FTE 3.0 tool was prepared by researchers from the Forest Products Laboratory and the North Central, Southern, Rocky Mountain, and Pacific Northwest Research Stations of the Forest Service.
